5.1 Equilibrium Constants and Rxn Quotients

Question 1

• What happens if k>1?

- What happens if k<1?

Answer 1

• if k>1 then the products are favored.

- if k<1 then the reactants are favored.

Question 2

What is the equilibrium constant equation?

Answer 2

Keq = [P]/[R]

equilibrium constant equals product over reactant.

Question 3

What phases are included in Keq equations?

Answer 3

• gases

- solids and liquids are excluded.

Question 4

Where do you put the coefficients in a Keq equation?

Answer 4

-do not put coefficients within the concentration brackets. i.e. 2CO = [CO]^2

Question 5

What is the only thing that can change Keq?

Answer 5

Temperature

Question 6

-What happens if KQ?

Answer 6

-if KQ shift right

Question 7

• What happens if the reaction is reversed?

- What happens if the reaction is tripled?

Answer 7

• if the reaction is reversed. it goes from 278 to 278^-1

- if the reaction is tripled, it goes from 278 to 278^3
